12 12 3. Installation 3.1 Selecting the installation site It is important that, whatever method of mounting is used, the point of measurement is truly representative for the entire solution. - Avoid an area where the measurement value varies significantly. GOOD GOOD HORIZONTAL - Ensure that the sensors are always immersed in the process liquid (not dry). - When selecting the installation site, first check that the liquid temperature and pressure meets the sensors and fittings requirements. - If the fitting is used in a tank with stirrer 15º 15º INCORRECT or agitator, or if it is placed in a fast flowing process, care must be taken that it is adequately supported to prevent any Fig. 3.1 Mounting position of sensors movement. - Install the fitting in a site where it can be easily maintained. The mounting position of the sensors must be within the area as shown in figure Installation Before installing the immersion fitting, check that all parts and accessories were supplied by Yokogawa. Ensure that there is enough spare around to withdraw the fitting for calibration and maintenance Hoisting eye type mounting On top of each fitting is a hoisting eye to withdraw from the process Flange mounting fitting If ordered, the immersion fittings are supplied with a flange for fixing in a tank. The flange is connected to the fitting as shown in the dimensional drawings. These drawings also show the configuration of holes. Table 2.

To prevent damage of the O-rings the nut and glands must be screwed HAND-TIGHT to the fitting. Prepare the sensor to be used in accordance with the directions for use. After that mounting can be made as shown in fig Attention: To prevent fouling of the contacts, it is recommended to screw the electrode cable on the electrode as soon as possible. Ensure that there is no moisture or dust in the connection sensor-cable.

15 Hole and 4-hole fitting Unscrew the protector complete with electrode holder from the lower end of the fitting (see figure 3.3). Unscrew the cap of an electrode mounting set. Pass the electrode cable through this cap and after that through the fitting. Mount the other electrode cables in a similar manner. Pass the electrode cables and the liquid earth cable through a hose connection, which is delivered with the fitting in a plastic pocket. Attention: Ensure that the cables have slack remaining in the fitting. The plug of the electrode cable must be ± 15 cm out of the lower end so that torsion will be avoided and sensor mounting is simplified. Protection hose Glue Electrode cable model WU20(D) Before screwing the hose connection into place HAND-TIGHT, some glue must be put to the screw end (see figure 3.4). Prepare the sensors to be used in accordance with the directions for use and mount them in the fitting as shown in fig For stable measurements the glass and reference electrode should be mounted in the holes nearest to the earth connection. As delivered the O-rings (2x) for water-tight sealing in the mounting holes are on the blanking plugs. These plugs are for unused holes. To prevent fouling of the contacts, it is recommended to screw the electrode cable on the electrode as soon as possible. ENSURE THAT THERE IS NO MOISTURE OR DUST IN THE CONNECTION CABLE- ELECTRODE. Liquid earth cable Electrode O-rings (11x3) Attention: To have slack remaining in the fitting the protector complete with electrode holder should be turned to the left before fixing HAND-TIGHT to the fitting.

17 Mounting kit option /R, (order nr. K1500BY) This mounting kit replaces the standard electrode mounting set so that Yokogawa refillable electrodes with a long glass shaft can be mounted in a fitting. The mounting set may be used at process pressures up to 3 bar. Higher pressure ratings require the standard mounting set and consequently, electrodes with DIN-dimensions. Figure 4.2 shows the mounting. KCI-Reservoir K1500FU Protection Hose K1500CJ/CK Note: The pressure on the KCI-solution must always exceed the liquid pressure. The refillable electrodes can be connected to a KCI-reservoir via a silicone tubing (see figure 4.2). The pressure on the KCI-solution and consequently, the liquid outlet of the electrode can be increased by mounting the reservoir on top of the fitting. This prevents penetration of the process liquid into the electrode. Electrode to be used* Order nr.

21 Salt bridge This reference electrode/salt bridge combination allows the measurement of ph and ORP (Redox) potentials with normal electrodes in those cases when: A. excessive contamination of the flow diaphragm is expected. The flow of the reference liquid through the diaphragm is increased by pressurising the container. Consequently, the contamination rate will decrease. B. the process to be measured cannot stand contamination with KCI. The salt bridge can be filled with several electrolytes, e.g. KNO3. C. measurement has to be performed at pressures up to 10 bar and temperatures up to 100 C. As the container with reference liquid can be pressurised.
